Overview
ISO/IEC 14496-5:2001/Amd 24:2009 is an international standard developed by ISO and IEC that focuses on reference software for audio-visual object coding. This amendment specifically introduces the reference software for AAC-ELD (Advanced Audio Coding - Enhanced Low Delay), a key enhancement for audio coding technologies. AAC-ELD is designed to support high-quality, low-delay audio compression suitable for real-time communication and interactive applications.
This standard is part of the MPEG-4 framework, addressing coding and decoding methods that ensure efficient audio-visual data handling. The amendment provides essential software tools to implement and test AAC-ELD encoding and decoding, promoting interoperability and consistency across platforms.
Key Topics
Reference Software for AAC-ELD
The amendment supply reference software aimed at facilitating the deployment and validation of AAC-ELD audio coding. It serves as a benchmark for developers to test codec compatibility and performance.Low Delay Audio Coding
AAC-ELD technology combines efficient compression with minimal latency, which is critical for applications such as video conferencing, broadcasting, and live streaming.MPEG-4 Audio Object Type Extensions
AAC-ELD extends MPEG-4 Audio Object Types to deliver enhanced audio quality at low delay, maintaining synchronization and clarity in interactive communications.Software Accessibility and Licensing
The standard includes software distributed in a structured digital format with licensing considerations. Permission and copyright compliance are required for software use and reproduction.
Applications
ISO/IEC 14496-5:2001/Amd 24:2009 and its AAC-ELD reference software are essential for:
Real-Time Communication Systems
Ensuring low-latency high-fidelity audio in VoIP calls, video conferencing, and telepresence systems.Broadcasting and Streaming Services
Delivering compressed audio streams with minimal delay and high quality for live events and online media distribution.Multimedia Production and Playback Devices
Integrating AAC-ELD codec support in hardware and software media players to enhance user experiences.Standardized Development and Testing
Enabling codec manufacturers and software developers to implement, verify, and benchmark AAC-ELD technology according to international standards.
